Diagnosis and management of hypertensive emergencies

Clonidine Lowers Blood Pressure by Reducing Vascular Resistance and Cardiac Output in Young, Healthy Males

“…Intravenously administrated Clonidine is used for the treatment of hypertensive crises [4][5][6], as well as for growth hormone deficiency testing in children, for assessing central α 2 -adrenoceptor function in adults [7,8], and for pharmacological testing in the diagnosis of pheochromocytoma [9].…”

Hipertensão arterial sistêmica no setor de emergência: o uso de medicamentos sintomáticos como alternativa de tratamento

“…In Brazil, 15% to 20% of urban adult population is estimated to be affected by high blood pressure (HBP) 1,2 . Data on hypertension crisis (HC) range from 1% to 27% [3][4][5][6][7][8][9][10][11][12] . Most centers do not count on specific standard dignosis procedures for hypertension crisis 13,14 .…”

Blood Pressure Recordings During Hemodialysis Access Interventions: Implications for Acute Management

“…There are several reasons why we did not use this agent to lower blood pressure in our cohort. First, clonidine can cause an uncontrollable fall in blood pressure . A precipitous decrease in blood pressure could deregulate cerebral circulation and create a catastrophe.…”

“…First, clonidine can cause an uncontrollable fall in blood pressure . A precipitous decrease in blood pressure could deregulate cerebral circulation and create a catastrophe. Second, the combination of opioids and clonidine increases the risk of intra and postoperative hypotension .…”

“…Second, the combination of opioids and clonidine increases the risk of intra and postoperative hypotension . Third, rebound hypertension is a real possibility with clonidine . In the context of percutaneous interventions, rebound hypertension imposed by clonidine could potentially become significant when blood pressure begins to increase after the effects of the medications used for conscious sedation wear off.…”
